PLANT ron THE MANUFACTURE. or METAL sHEETs onsTRrlrs( Application led August'Z?, 1923. Serial No. 659,460.

The invention described herein relates to improvements in plantsfor manufacture of sheets or strips from ingots, blocks, or slabs, as hereinafter more fully described and claimed. y

1n the'accompanying drawings forming a part of this specification, Fig. 1 is a diagrammatic view illustrating the mannerof combining the several reducing feeding, annealing and shearing elements embodied in the invention claimed herein; Fig. 2 is a plan view showing portions of the cooling bed and the feed tables arranged on opposite sides thereof; Fig. Sis a sectional elevation on a plane indicated by the line IIL-III, Fig. 1;

' and Fig. 4 is a sectional detail view of means for moving the sheets or strips across the cooling'bed. l

In the practice of the invention a feed table 1 is arranged along in front of and in such proximity to one or more heating furnaces 2 that articles `to be reduced can be readily withdrawn from the furnace and placed on the feed table which extends tothe universal mill indicated at 8. As reduction in this mill is effected by back @and fortl'x passes, the rollers of the section of the feed table adjacent to the universal mill are reversible and operated to feed the article to the mill on the forward pass and receive it from the mill on the back pass. In the rear of the mill is arranged a second feed table 4 having reversible rollers. After reduction in the universal mill, the article may be shifted to a cooling bed or fed by the table 4L' tov s preferred that the last stand of the continu-A ous mill should be driven independently of the other sands which, as shown in Fig. 1, may be driven from a common motor. A feed table 6 is arranged at the delivery end of the continuous mill for delivering the article to the cutting mechanism 7.

As is well known to those skilled in the art, the slab can be so rolled is a universal mill as tovproduce any desired width of sheet or strip; dependent, of course, on the dimensions of t e mill, and also any desired gauge e'. g. ene eighth of an inch or thicker, but it has been found that toreduce a slab to awidth of thirty inches or less in' a universal mill requiresthe employment of very long feed tables having reversing rollers 4to effect the back and forth passes. Hence in the universal mill the article is reducedby thepvertical rolls lto or approximately to the desired width but only a partialreduction to gaugelor in thickness is effected by the universal mill, final reduction to gauge being effected. by Vthe continuous. mill. the operator knowing the most eiiicient rate of reduction in thicknesseffected in the several stands of the' continuous mill, willrel ducesin the universal mill to a gaugev or As. for example,

thickness, that by the action of the two-high f mills will reduce thearticle `to the finished gauge.

When sheets of a greater width than thirty inchesare desiredthe slabs are reduced .to the desired gauge or thickness and the sheets are Vthen transferredjby @lick-offs?? indicated at v8 to the cooling tablevQfeXtending at Vright angles to the feed table. Any suitable vmeans known inthe art may be employed for shifting the sheets across the ccol- Y ing bed onto` the feed'tables 10 having re` versibly driven rollers. As shown in Figs. 3 and 1, such shifting means may consist of bars 11` provided with lpivotally mountedV dogs 12 adapted to be tipped and pass under the sheet when the bars are mo-ved to the left' in Fig. 3, but will engage the rea-r edge of the sheet when the bars are moved to the right. A convenient means for reciprocating the bars consists cfa lever 13 having their free ends connected to the bars and connected by links 14 to kcrank arms 15 o-n a driven shaft 16. Y

yAs in most cases it is desirable to anneal the sheets, a continuous annealing furnace of any suitable construction 17 is arranged at one end of the feed table 10, and by pref` erence a feed table 18 is arranged at the discharge end of the furnace to carry the sheet to the side shears 19 and to and through Y vIn lieu of cooling the strip as it comes from the continuousmill, it may be desired to trim the edgesand cut it into sectionsor te sanear it and then trim it and eat it Ta this end a `table 2l is arranged at right angles to the feed table 6 as shown in Fig. 1 and the strips as they come from the continu-ous mill are pushed laterally vfrom the feed rollers and onto the table 2l by a kick-off, andV then moved across said table onto a feed table l() bymeans similar tothat shown in Figs. 3 and 4 and hereinbefore described. Y The feed table 10, preferably extends across Vthe ends of the tables 9 and 2l and at the end yoppositefthat .atgwhich the .annealing furnace Ais located, are arranged sideandsquaring shears 22 and 23.

As hereinbefore stated, the feed rollers of the'table l0 are reversible, .rendering it possible to feed the sheetleither 'through the annealing furnace or if annealingfis notdesir-ed, the .sheet may be fed in the opposite direction .and be trimmed and .cut by the shears 22 and 23. And further, the strip formed by the continuous mill can be fed either directly to the; shears v22 and 23 or be moved ,in the `opposite `direction through the annealing furnace and vthen trimmed and cut.

I claim herein as my invention:

llfIn a rolling mill plant, they combination of furnace, a ainiversal mill, vreversible feed tables arranged on opposite sides of the universal mill, a feed table arranged approximately parallel with the feed table on the delivery side of the universal mill, means for transferring articles from the latfer ontothe second feedA table, and van annealing furnaceiadapted to receive van articlejfrom the second feed table.

2. In a rolling mill plant the combination of a furnace, a universal mill, reversible feed tables arranged cn opposite sides of the universal l-m'ill, a continuous mill consisting of a plurality of twoehigh stands of rolls adapted to receiveV articles from the feed table-onthe .delivery side 'of the unirality of two-high stands of rolls, a feed table on the gdelivery vside of the-continuous mill, ,a reversible feed table arranged approximately parallel -With the feed tables on the delivery sides .of the universal and con f tinuous mill,means for shifting articles .flaterally from said mill tables to thev second .feed table, a continuouskannealing furnace at one end of the second feed table and trimming and squaring` shears .arranged in operative vposition adjacent to the other end of said feed table.
